IMPROVEMENT IN MACHINES FOR CLEANING GRAIN, NUTS,

Specification forming part of Letters Patent No. 139,248, dated May1873; application filed February 20, 1873.

To aII whom it may concern:

113e` itknown that I, J osEE JOHNSON, of the city, county, and State ofNew York have invented an Improved Cylinder Machine for Cleansing Seeds,Grains, Nuts,'Fruits, Castings, &c., all of which is clearly and` fullyexplained in the following specification taken in connection with thedrawing .forming part y thereof, and in which the same letters indicateo like parts in all the figures.

"My invention consists in mounting or suspending a cylinder in or bybelts, which not ,ff-only support but also at the same time rotateeither case maybe attached to the inner side of the cylinder to runeither longitudinally or diagonally, each mode being better adapted forspeciiic purposes. When the cylinderis of any great length, a hoop maysurround its center to give strength to the same. In Figs.

but, instead, there is a rim, e c, affixed to each end of cylinder a,which serve as pulleys, Without arms or centerbearings. b b are endlessbelts which surround pulleys c e, and also .y y the pulleys c c, fromwhich `and by which the cylinder a is suspendedand driven. dis the` Vdriving-shaft, and f is the driving-pulley.

This construction and arrangement enables the cylinder a to be fed andemptied when the cylinder is revolving, and cylinders of various lconstructions, for various purposes, may be ex- I changed at pleasure,withoutfchange of pulleys or belts in any manner. It is further seen inFigs. 2 andB that theopening in one end of the cylinder is larger thanthe one in the opposite end; hence, in some kinds of articles beingcleansed, if 'the cylinder is fed at the v small opening,the cylinderempties itself automatically at the-larger opening.

What I claim as new, and desire to secure The cylinder a, suspended by,mounted in," f l and driven by, the belts b b, substantially as" y andfor the purposes described.

JOSEE JOHNSON.
